Rotor chainring fit question(s)...

[brokenladder]

anyone else experience fit problems with the rotor chainrings? in particular i have a problem fitting a 36t on my ti eriksen cross frame -- chainring hits the chainstay during a rotation (sram force crankset and gxp bb). if i drop in two (1mm) spacers it seems to clear the chainstay. too much of a hack? risky relative to the crankset? other ideas/concerns?

running the rotors on my mtb and road bike without issue. really like them so far (notwithstanding this issue)...

thanks in advance for any ideas/experiences relayed!

Have you considered a longer bottom bracket? The oval chainring has a longer major axis so it would naturally need more clearance than a standard 36T ring. Apparently you must not have a lot of extra clearance -- not all that uncommon for ti frames; and more so if made for fatter cross tires.
